Market, called universal fast charging, voltage 4 ~ 6V, current 0 ~ 700mA. High voltage high load rapid change, of course, but too easily lead to the battery current to shorten battery life and high current will be a great heat, the temperature is too high causing the battery to explode easily is the security risk the most serious. 2 years ago have been several times since the summer high temperature, resulting in cell phone battery exploded and injured more people, we are interested can look to see, security is not really a joke. Finally, a conclusion: the charger is not charging faster, better.
Since the explosion of the battery temperature is too high after the news, many manufacturers have made a change in power, increasing the pressure limiting current limiting resistor, so that all under control voltage and current, and temperature is not high, dell, but the tension is too low and the battery can not be filled, one with an office half a day without electricity or high load capacity Battery is now a 1-2 full days as unhappy long after the battery capacity will decrease, affecting life. Recommend the use of major brands of chargers, such as land and sea connections, hair flying back and so on. Recently, the market has a new universal tax, Bo Tao Bo U.S. Department of the mark, listen to people say that if manufacturers in Shenzhen Bognes technology, plant Sakata. Bo Tao of three colored lights and chargers tested the charger I bought, very good electrical properties in the standard range, and fly back hair, and sea links and other major brands neck and neck . More cows enter, 1 5 m, all OK, a small shell rupture, 2 meters 5 times still no major problems. Still down from the fourth floor and the shell are rotten, the ground state is streaking, and here the power, measure, and gives no problems with the electrical properties, carefully reviewed the electronic components and joints welding, really solid materials. Dell Latitude E6400 battery, Dell Latitude E6500 battery, Ordinary universal charge and speak still down, and down just outside the solder joint on the whole machine does not work. My only regret, surprise, Bo Tao, or the appearance of color to the old egg-shaped, not beautiful, looking forward to the future, it will be even more beautiful. Price back hair, sea and land routes for cheaper, the cost is very high, recommend to try next.
